What happens when the chemical bond that holds the third phosphate is broken?
The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).
What is phosphate bond?
The structural structure of nucleic acids, including DNA and RNA, is composed of the sugar-phosphate backbone.
This molecule's directionality is determined by this backbone, which is made up of alternating sugar and phosphate groups.
Nucleotides make up DNA and RNA, and they are connected to one another in a chain via chemical interactions between their neighboring nucleotides' phosphate groups and sugar bases.
Therefore, The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).

Answer: Adaptation
Explanation:
A polar bear has thick, white fur that camouflages it when it sits on snow. Which type of adaptation is this modification?
A. structural
B.natural
C.functional
D.behavioral
Which on is it?
Answer:B Natural
Explanation:Camouflage is a adaptation which animals use to blend in with their surroundings in order to protect themselves from the predators and hunters. This also gives them a better chance of survival and easy mode of hunting for food.
For example: white fox hides in the snow from the predators
Camouflage is a clear example of Physical or Structural adaptations.
-Body shape, color and body patterns are the adaptations that assists both predators and prey to camouflage
-As in the example mentioned, the polar bear with its white fur hides in the snow and waits for the right time to attack its prey without being seen

A _________ is an organic compound that must be obtained from the diet and is needed to sustain life.
A Carbohydrate is an organic compound that must be obtained from a balanced diet
Carbohydrates are food nutrients which are also organic compounds which are required for the sustenance of life because they are a very vital source of energy which the body requires for it to function properly and efficiently.
Other organic compounds are Proteins, lipids and Vitamins because they all contain elements of carbon in them. But for the Human body to be active it requires energy and the most important source of energy to the body is Carbohydrate
Hence we can conclude that Carbohydrate is an organic compound that must be obtained from a balanced diet.

What are some things water will adhere to? and What are some things water will not adhere to?
Answer:
1. Water has an amazing ability to adhere (stick) to itself and to other substances. Hydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH3), water (H2O) and hydrogen fluoride gas (HF).
2. In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Respiration taking place in presence and absence of oxygen has different end products. Aerobic respiration has the end products as carbon dioxide and water, alcohol is the end product of anaerobic respiration.
What is respiration ?It is the process in which the complex substituents are broken into simpler products in the presence of oxygen and absence of oxygen in order to produce energy.
In the aerobic respiration processes like glycolysis takes place where the glucose breaks down into 4 molecules of ATP with the consumption of 2 ATP molecules. 1 glyceraldehyde molecule is produced from the glucose that is 2 glyceraldehyde molecules are produced. Total of 4 ATP are produced.
Alcoholic fermentation is the anaerobic respiration that says the anaerobic respiration where the glucose is broken down into alcohol and water. In the anaerobic respiration, excess of alcohol gets broken down into lactate.

Look at the diagram. Name organ 1.
Answer:
Organ 1: Stomach
Explanation:
The stomach holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a useable form. The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The large intestines are to absorb water and salts from the material that has not been digested as food and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption have already taken place. The small intestines have three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body. The small intestine is part of the digestive system.
